Photographic print, 10 x 8 inches including black mount.
Subject: Hands up if you know what this is.
Hands up if you know where this is.
Hands up if you know the number of people who pass it without even noticing.
Have I got you stumped on the last one?
This is the cutting head of a tunnel boring machine. It is on display at Cutty Sark DLR station in Greenwich, London, and was used to bore the tunnel under the Thames from the Isle of Dogs.
And yet people see this print at a market less than a 100 yards from the station and ask what it is, and where it is, and have often walked past it to get to the market. Perhaps I worry too much about good photography being about seeing things differently; perhaps simply seeing is enough.
All of which is completely irrelevant to the image. It's an unusual variant on patriotic red, white and blue. It celebrates British engineering dating back to the methods of Brunel. And I quite like it (which also is irrelevant).
